If I read your first post correctly, you mentioned 2 males, 6 normal females, and 2 morph females. Since I was only suggesting switching one morph female for a different one, that's still only 4 females to a male. Or did I get lost somewhere?
From what I've read (I've not done any breeding myself yet), if you'll have 4 or 5 females to a male, the males can handle it and probably more. Even if one of your males turns out to be less robust in that department, I'd guess your other one would likely be able to pick up the slack.
Here is a link to a couple of threads on the subject; if you dig around you'll find more.

Not trying to argue that you should breed your males to lots of females each, just that it apparently can be done without harm, and since it appears you want to try to get as many clutches as possible, that seems to way to go...
